EMPIRE®"s USB data cable provides the ability to charge (device must support this function) and sync your device to your Mac or Windows PC. The cable offers error-free data transmission of contacts, music, ringtones, and other types of media at fast data transfer speeds. Devices that use USB for power don"t need a separate power supply, conserving space and keeping power outlets free. Software and USB drivers are not included. EMPIRE®"s retractable car charger keeps your devices battery charged on the go when plugged into any 12V cigarette lighter socket. It features an intelligent IC chip that helps prevent your device from overcharging, which could cause damage to it. The 4 ft. retractable cord easily gets out of your way when unneeded by simply touching a button that"s on the charger itself. Small enough to fit into a bag or purse, you can conveniently bring this along wherever you may be traveling to. Charging time varies depending on battery size (mAh capacity). Charging port on device may differ in shape from charging tip, depending on phone manufacturer.
